SIDE BEARING- FOR CABS.

To all whom it may concern: 7

Be it known that we, LEE W. BARBER and EDWIN WV. VVEBB, citizens of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in SideBearings for Cars; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

vide an improved side bearing for railway cars, and to such ends,generally stated, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, likecharacters in dicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a plan view of the improved sidebearing; Fig. 2 is a side elevation thereof; Fig. 3 is a section takenon the line 42: m of Fig. 1; and Fig. 4 is a section taken on the line waz ofFig. 1.

The housing is made up'of two sections, to-wit, an upper and a lowersection, and both of these sections are preferably castings, althoughthe top member, especially, might be a pressed steel member. The lowerhalf 1 of the housing has a flanged base adapted to be riveted, bolted,or otherwise rigidly secured to the ends of a truck bolster. The body ofthe said lower member is a box-like structure cast integral with thebase and suitably ribbed, and in its side walls, it is formed withapproximately semi-cylindrical recesses adaptedto receive the ends ofpins 2 on the intermediate portions of which rollers 3 are journaled.The said seats for the ends of the pins 2, above the horizontal plane ofthe axes of the pins, flare upward slightly, so that they are adapted tobe drawn from the sand in the process of casting. The base member 1,just below the rollers 3, is cut through at 4, so that sand and dirt maywork downward out of the box, it being assumed, of course, that thebolster will have some provision, such as a passage to permitprecipitation of the dirt.

:drical. Our invention has for its object topro- The upper portion 5 ofthe housing is an approximately H-shaped structure which fits upon thetop of the box-like body portlon of the lower member 1 with itsbifurcat'ed end portions embracing the upper portions of the rollers 3,and resting on or immediately over the ends of the pins 2, being, asshown, provided with seats for engagement with the. pins, which seatsare preferably a little less than one-half cylin- -At the outerextremities ofits seats, the inner and outer walls of the said uppermember 5 extend below and outward of the ends of the cooperating pins 2to'aflord lips 6 that positively hold the said pins against endwisedisplacement. It therefore, of course, follows that the said pins mustbe inserted in, position before the upper member 5 is secured to thelower member 2. As a simple and eflicient means for rigidly connectingthe said members 1 and 5, they are provided at the central portions oftheir inner and outer sides with engaging horizontally projectingflanges 7 rigidly united by rivets 8. Thus it will be seen that when theupper section is applied to the lower section of 'the housing, the pinsare positively held in working position.

As a highly important feature of this invention, the top of the housingis formed with a smooth flat upper bearing surface 9 that is normallyslightly below the upper surface of the rollers 3. The roller engagingbearing surface carried by the body bolster of the car will normally beengaged with the upper surfaces of the rollers 3, but it is adapted todrop down into engagement with the said flat bearing surface 9 wheneverthe rollers are broken or lost out in any way, or for any reason, havebeen removed. It is, therefore, important that the said bearing surface9 stands very close to the upper surface of the rollers so that the playbetween the upper and lower side bearing members on the truck bolsterand body bolster, will not vary much under the different conditionsabove noted. The bearing surface 9 is therefore in the nature of anauxiliary or reserve bearing element which becomes useful in emergencyand prevents the side hearing from becomingthe pins or rollers or thepin engaging seats,

the said bearing surface 9 will be brought into action.

What We claim is: g

1. A side bearing for cars comprising a* housing made up of rigidlyconnected up per and lower members, a pin seated in the lower memberwith freedom forlateral and endwise displacement and held in position bythe upper member against lateral and endwise displacement and a rolleron said pin.

2; A side bearing for cars comprising a housing made up of rigidlyconnected up- 1 per and lower members, said lower nieliif her havingopen toppedpin seats extending completely through its side walls, pinshaving their ends seated in said open seats with freedom for lateral andendwis'e' di's'-' flanges that overlap the ends" of said pins" and holdthe same against endwise displacemeat", and rollers on said pins.

3. A side bearing for cars comprising a housing made up of upper andlower memb'r's; said upper member having a horizontal top bearingsurface, a pair of rollers journaled in said housing with their uppersurfaces at the same altitude slightly above said top bearing surface,said upper and lower members having horizontal flanges located betweensaid rollers and below said top bearing surface, and rivets rigidlyconnecting said horizontal flanges.

In testimony whereof we afiix our signatures'in pr'senceof twowitnesses.
